1. Equivalent Ratio Meaning

Key Concepts & Definitions

  • Equivalent ratios : Different ratios that show the same comparison.

Essential Points

★ Must-know

📌 An equivalent ratio is created by multiplying or dividing both numbers by the same non-zero number.

Further detail

  • The ratios 2:3, 4:6, and 6:9 are equivalent because each ratio is formed by applying the same multiplier to both terms.

Same comparison, same multiplier

2. Finding Missing Ratio Numbers

Essential Points

★ Must-know

🧮 Formula — The multiplier equals the new number divided by the original number.

🔄 Process — To find a missing number in an equivalent ratio, match corresponding numbers, divide the new number by the original number to find the multiplier, and apply that multiplier to the other term.

  • In 4:
    • 7 = 20:□
    • the multiplier is 20 ÷ 4 = 5
    • so the missing number is 7 × 5 = 35
